[PATCH] Rename "sun" variable to avoid conflicts on Solaris

["Christian Biesinger via gdb-patches" <gdb-patches@sourceware.org>]

A Solaris system header has a #define for "sun".  This renames
that variable to avoid the conflict, fixing a build error with
--enable-targets=all on Solaris.

gdb/ChangeLog:

2019-12-18  Christian Biesinger  <cbiesinger@google.com>

	* fbsd-tdep.c (fbsd_info_proc_files_entry): Rename local var
	"sun" to "saddr_un".
